8 %, 9 %, 10 %, 11 %
12 %, 13 %, 14 %, 15 %
The valve will only be

value has changed by more
than the set value, compared
to the last positioning. This
enables frequent, small
positioning increments to be
suppressed
Open from actuating
value*
0.4 %,
Valve is opened even with
minimum actuating value.
5 %, 10 %
15 %, 20 %, 25 %
30 %, 35 %, 40 %

the set value.
This setting prevents possible
